Simulation and Test Analysis of Ride Comfort on Air Suspension of Large Bus

Based on the dynamic theory and taking 1/2 bus model as the simulation object,the authors use the Matlab software to set up the air suspension system model.Simulation and analysis of it are carried out with the model,and comparison between simulation result and test result is done.It is shown that the dynamic model of the bus is right and the bus ride comfort can be analyzed and evaluated by the simulation model,with the technology,predication and analysis of vehicle ride performance during design phase are realized.And the method and the way of improving vehicles smooth running are proposed.
